HYDROGEN PRODUCTION BY WATER DISSOCIATION IN THE PRESENCE OF SNO USING THE SNO2/SNO COUPLE IN A SERIES OF THERMOCHEMICAL REACTIONS

摘要

The invention relates to a method for preparing hydrogen that comprises a hydrolysis step (C) of solid SnO for producing hydrogen, in which the hydrogen thus produced is stored, recovered and/or upgraded, and in which the solid SnO used is obtained by the following steps: (A) thermal reduction of SnO₂ into SnO in conditions yielding gaseous SnO; and (B) cooling the gaseous SnO thus produced to a temperature lower than or equal to %50° C. The invention also relates to devices and equipments for implementing said method.
